Ok; I thought you may have some strange python installation. Sorry!

Hm. Mac OS X's are weird sorts of unices, aren't they? (BIG TROLL 
DETECTED!) ;)

> Applications have essentially no environment at all, but they do understand environment variables.  Applications are in their own world, so to speak.  There is a hidden mechanism for setting Application environment, but I don't want to spread that as it is cluncky to use (need 3rd party apps for a nice GUI front end), and is not well documented, if at all.

Yes, it makes sense! So? Does it work?


Funny: in DOS and windows (another strange kind of OS, next troll), the 
current directory of any executable is in the path. And in unices (at 
least the ones I know), the current directory (.) is never in the 
path... I never figured it out on a Mac.

Yes, it was...
